Geography
Île Belle is located between Hardricourt and Mézy-sur-Seine on the right shore and Les Mureaux on the left one. It is the north part of a five kilometer long island formed by the fusion with two other former islands, Île de Mézy and Île de Juziers
It is separated upstream from Île du Fort by the Saint Côme arm. It is administratively attached to the commune of Meulan-en-Yvelines. The island is linked to right shore by a bridge over the Melan arm, by the Rhin et Danube Bridge to the left shore and by the Saint-Côme Bridge to Île du Fort.
Within Île Belle are located a swimming pool administered by an intercommunal syndicate and a hotel of the brand Mercure located in the ruins of an 18th-century castle, who belonged to Armand-Jérôme Bignon, the royal librarian of Louis XV, as well as a cynodrome devoted to dog races.
This brief starts where responsible research should: with the source description of “Île Belle” as island in Yvelines, France. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the places & architecture register because the source frames it as island in Yvelines, France. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Place names and jurisdictional language are key evidence: both can reveal earlier catalogue descriptions and overlooked record series. The source revision retrieved here is dated Apr 7, 2026. The linked authority identifier is Q3593011. Authority coordinates are 49.000, 1.899. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank.
Modern boundaries and familiar names can conceal earlier jurisdictions or structures that do not align with the present site. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
